one of these years ago, and it used to work pretty well. The Quadra has
a PDS type slot.
That slot will take a SCSI accellerator card, which will essentially
transforn your 950 into a WGS95.
Please don't disgrace this beautiful 68K machine with PPC upgrades. It is
pretty much begging for an A/UX install.
What Joost said, pretty much!
That's one of the last and among the most powerful 68K Macs ever. Why
turn it into an underpowered, poorly-performing PowerPC machine?
It would be a lovely machine to run MacOS 8.1 on - and having that
dual-booting with A/UX would also be very cool indeed. With relatively
easy-to-find and inexpensive 4MB SIMMs, you could fit it with 64MB
RAM, which is plenty for OS8 and would get you up and running with
A/UX.
The 950 is one of my favorite Macs, I have 5 of them (one original mint
WGS95, 4 normal 950's). Nothing runs A/UX as well as a WGS95 with the full
512Kb cache installed on the PDS SCSI card (for a server anyway). There are
68K upgrades for the 950's I have one clocked at 50Mhz with cache:

The 601 PPC upgrade cards are not that bad, I use one in a 950 because it is
an AVID video editing setup and requires it (you need more then 3 Nubus
slots for all the cards involved). There is a cool PDS SCSI card for the 950
:

and of course the coolest PDS upgrade the Daystar 601-80 with 4 x 72 pin
SIMMs and 1MB cache the 68K side can also use. So if you max out the 950
with 256MB of 16MB 30 pin SIMMs and get the Daystar card with another 128MB
of RAM you have a 68K Mac that can use 384MB of RAM! You can boot with or
without the accelerator running by using the Daystar control panel so you
don't really ruin anything unless you need that Nubus/PDS slot for something
else.
Mostly I like the 950's because of all the cool upgrade cards I can stick in
them. It used to be you couldn't give those models away but one recently
sold for $200 + expensive shipping so somebody must have wised up about
their collectability.
